A man pushing a mop across a floor causes it to undergo two displacements. The first has a magnitude of 146 cm and makes an angl
svetlana [45]

Answer:

B = 191.26 cm

θ = -14.73°

Explanation:

given,

magnitude of the first displacement(A) = 146 cm

at an angle of 124°

resultant magnitude = 137 cm

and angle made with x-axis by the resultant(R) = 32.0°

component of A in X and Y direction

A x = A cos θ  = 146 cos 120° = -73 cm

A y = A sin θ = 146 sin 120° = 126.4 cm

now component of resultant in x and y direction

R x = 137 cos 35°

    = 112.2 cm

R y = 137 sin 35°

     = 78.6 cm

resultant is the sum of two vectors

R = A + B

R x = A x + B x

B x =  112.2 - (-73) = 185.2 cm

B y = R y - A y

B y = 78.6 - 126.4 = -47.8 cm

magnitude of B

B = \sqrt{B_x^2+B_y^2}

B = \sqrt{185.2^2+-47.8^2}

B = 191.26 cm

angle\theta = tan^{-1}\dfrac{-47.8}{185.2}

θ = -14.73°

What is the difference between soldering and solder? <br>​
andrey2020 [161]

Answer:

Soldering is a technique or a process to bond metals with the help of solder. Solder is a metal alloy with a low melting point and is often regarded as the base metal for soldering. The piece or structure that is being bonded together does not get hot enough to melt and this is where solder (base metal) comes into play and creates the connection.

The material that transmits most light is d) clear glass.

Explanation:

Depending on whether objects can transmit light or not, they can be classified into three types:

  • Opaque: an object opaque does not transmit light at all (light cannot pass through an opaque object). Examples of opaque objects are metals
  • Translucent: translucent objects allow light to pass partially through them. Examples of translucent objects are fluids
  • Transparent: transparent objects allow light to pass through them. An example of transparent objects is clear glass

In this problem, we have the following objects:

  • Umbrella: it is opaque, light does not pass through it
  • Blanket: it is opaque, light does not pass through it
  • Mirror: It is opaque, since it reflects light (light does not pass through it)
  • Clear glass: it is a transparent object

Therefore, the material that transmits most light is d) clear glass.

A block of copper with mass 0.500 kg is heated to 400. degrees Celsius from 290. degrees Celsius. The specific heat capacity of
Aleks04 [339]

Answer: 2.13 E 4 J

Explanation: Heat absorbed = mass * specific heat capacity * change in temperature

= 0.5 * 387 * (400 - 290) J

= 0.5 * 387 * 110 J = 21285 J = 2.13 E 4 J
